I've been living with my step father for over 10 years now and even since the beginning he had this irridibility about him that he hates me and my mothers side of the family literally. Over these years i, after all that, hate him too, but in the pass year or 2 his barrier as you can call it or his fine line has slowly progressed where he would just be more expressive. If you are kind of lost well he is somewhat a verbal abuser, kinda, always saying stuff about my mother's side of the family sometimes little things about me, don't worry I ignore it don't let it get to me, but this topic is mainly concerning my mother because his fine line is I can tell that its getting to my mother and I wanna know if its a mental condition where he is this way or if he was just naturally like this. Because he acts nice I guess if he needs sometime like translated maybe, he doesnt speak english, or ask a favor, other times his just some what happy , other times he gets angry out of no where, he has a high temper. Not to mention he hates my family for no appearant reason. I consider my family as really really nice people I mean not like super pacifist where they forgive everyone and everything but they are really nice people but he hates them for no appearant reason and he doesn't say stuff about them in their faces he rants and goes on about stuff at home and make kidding about stuff seriously and repeatedly. He also can't stay quiet alwasy talking. I might hate him but I my concern for my family mainly my mother cause she's like around him, even though I know he wouldn't do anything physical, that this might affect my mom in other ways. If this is some sort of mental condition please tell me and if not please note it. Thank you very much. If this isn't specific or clear enough please fill free to ask or tell me.
